[Evolution] Import form mbox fails

[Patrick Marquetecken <patrick marquetecken pandora be>]

Hi,

i need to import some mbox files from evolution into Sylpheed.
Some mbox files i don't see, and some if i import them they have the wrong files!

I have  moved the mails in to another subfolder in evo but i still can't import them.
This is really important for me, it contains several important mails.

TIA
Patrick
